1.4 Device Information

REF80 is a buried zener, internal heater compensated voltage reference. The device is designed with an extremely low temperature drift and long-term drift. REF80 is also a low noise device. This allows REF80 to be used with the highest precision of ADCs and DACs and in many calibration applications. REF80 has a TSET pin which allows the user to set the internal temperature at a temperature different from the default temperature. REF80 does not require external resistors to set the output voltage or for other device operation, so it can greatly simplify board design.
